You can do power factor correction on motors and transformers.
All my welders and air compressorsare power factor corrected.
I tried to power factor correct cheap low power factor florescent lights, but adding capacitors made the power factor worse.
Might be able to power factor correct magnetic ballasts some what.
Cheap power supplies create phase distortion.

From what I was reading in that article, in small power supplies, active PFC circuitry is both fragile and expensive.
From a facilities standpoint, it's probably cheaper (and more reliable) to correct the power factor at the transformer feeding lighting panels than it is to have individual pfc at each fixture.

Allie Moore and I have a combined carbon footprint much smaller than that of one average American...
